Century Eastern Wonders is a great step up from Century Spice Roads. it is a play alone game - which you can also combine with Century Spice Road for a combined game. Firstly though the base game of Eastern Wonders. It has taken all of the good things about Spice Road and improved on it all. There is a lot more player interaction, the game is ever changing as the board is made up of hexagons which are randomly placed each game, there are some awesome bonuses you can pick up which you want to get first - and that is a hard decision as you want them all. The artwork is improved from the original games as well. If I had to pick just one out of the first two Century games for me it would be this one. At the time I am writing this the 3rd one has not yet been released.
When you join the two games together to play it doesn't really feel like a new game, it is a combination of the two. It does make your brain think even more as you now have more choices to try and gain points to win the game. It is nice though to have the option to join them together to create new options for the game. I do recommend Century Eastern Wonders, with it's basic rules, it's player interaction as you move across the board, with it's every changing player board, with it's fantastic player bonuses and the hard decisions you have to make in the game - it is a perfect game for each collection (With or without any other Century game)
